With the top (stacked bar) plot, you can view the total sequences published by continent since the beginning of the SARS-CoV-2 outbreak.
Try clicking on one of continents in the graph's legend, it will highlight only that region in the graph.
Using the dropdown menu above the second (Mutation Allele Frequencies) plot you can select the mutation you are interested in and view its frequency across time and across continents.
You can use the main plot to view all mutations across the genome by total frequency and then come back here to view its temporal/spatial spread.
It is important to understand the frequency of sampling for a given continent or week when looking at the frequency of a mutation. Use both plots to assess how sampling may skew the reported allele frequencies.
We will update this page with links to acquire the raw data for this analysis ASAP. If you require it urgently, contact daniel.ward1@lshtm.ac.uk.
